[Progress and perspectives in pediatric oncology: 30-year experience of the clinic of pediatric oncology].

Seventy percent of cases of Hodgkin's disease and 65% of those with kidney malignancies can be cured due to application of modern procedures of oncopediatrics. More intensive modalities have to be used for treatment of generalized forms of non-Hodgkin's lymphoma and sarcoma of Ewing. The rates of 3-year survival have risen to 70% in patients suffering acute leukemia following introduction of the new Protocol procedures. Infantile mortality from malignancies has been halved for the past 5 years (from 8.2/100,000 to 4.2/100,000) thanks to the taking of said measures and restructuring the oncopediatric service.
